低功耗AI晶片新星Ambiq擬紐約上市




Ambiq Micro計劃於紐約證券交易所上市,股票代號“AMBQ”

專注於邊緣人工智能(Edge AI)超低功耗半導體的供應商Ambiq Micro Inc.,近日向美國證券交易委員會(SEC)提交了首次公開招股(IPO)申請,計劃在紐約證券交易所掛牌,股票代號為“AMBQ”。根據申請文件,這間位於美國奧斯汀的公司擬發行680萬股,發行價格區間介乎每股22至25美元,若以最高價計算,公司估值可達約4.26億美元。

此次承銷團隊包括美銀證券(BofA Securities)、瑞銀投資銀行(UBS Investment Bank)、Needham & Company及Stifel。公司亦授予承銷商51萬股的超額配售權,若全數行使,將為公司帶來額外資金。

產品優勢及市場表現

Ambiq的晶片功耗較傳統產品低2至5倍,迄今已出貨超過2.7億台設備。2024年內,4,200萬台晶片中超過40%用於運行AI算法,主要應用於可穿戴設備、數碼健康、智能家居及工業邊緣系統等領域。

公司營收增長主要來自中國大陸以外市場,2025年上半年淨銷售額同比增長超過56%。相反,同期中國市場銷售額則大幅下跌約84%,反映公司正在調整其市場策略,減少對中國市場的依賴。

根據初步財務數據,Ambiq預計截至2025年6月底的六個月內,毛利率提升至46.3%,較去年同期的35.7%顯著增加。毛利額介乎1,520萬至1,590萬美元之間,顯示隨著系統單晶片(SoC)及軟件銷售的整合,營運槓桿效應明顯改善。

技術平台與未來發展

Ambiq的產品線包括Apollo系列及正在開發中的Atomiq SoC系列,均基於其專有的「亞閾值功率優化技術」(Sub-threshold Power Optimized Technology,簡稱SPOT)平台,旨在提升AI工作負載的能源效率。Atomiq雖仍在研發階段,預計將成為公司迄今性能最高、功耗最低的產品。

儘管公司呈現增長態勢,Ambiq亦提醒投資者需留意若干重大風險,包括對台積電(TSMC)代工的高度依賴,以及缺乏長期客戶訂單承諾。此外,公司在轉向公開市場財報標準過程中,已發現內部財務控制存在重大缺陷。

展望未來,Ambiq計劃將其SPOT架構擴展至專用AI處理器及應用特定晶片領域。管理層相信,若能推出可授權的SPOT平台,將使公司成為預計於2028年達225億美元規模的邊緣AI半導體市場中的核心低功耗技術供應商。

評論與啟示

Ambiq Micro的策略及技術路線清晰地反映出當前半導體產業對於低功耗、高效能AI晶片的強烈需求。其SPOT技術的核心優勢在於極大地降低功耗,這不僅適用於電池供電的可穿戴設備和智能家居,亦是工業物聯網及邊緣計算不可或缺的基礎。隨著AI應用越來越普及,尤其是在對能效要求嚴格的領域,Ambiq的技術有望贏得更多市場份額。

然而,公司對台積電代工的高度依賴是一大風險,尤其在全球供應鏈緊張及地緣政治不確定性增加的背景下,這種依賴可能限制公司靈活調整產能和成本。此外,內部財務控制的問題亦需嚴肅對待,因為這將直接影響上市後的信譽和投資者信心。

值得留意的是,Ambiq正在逐步減少對中國市場的依賴,反映其在全球政治經濟環境變化下的調整策略。這種市場重心轉移雖然短期帶來銷售下滑,但長遠看有助於分散風險。

總括來說,Ambiq的IPO不僅是其融資擴張的里程碑,也代表了低功耗AI晶片領域的一個重要技術推進。對香港及全球科技投資者而言,這提供了一個觀察新興AI半導體趨勢的窗口,尤其是在邊緣計算和物聯網設備日益普及的時代背景下。投資者在評估其潛力時,應同時關注其技術創新與市場風險的平衡。

She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection.
